[0002]

2. Description of the Related Art In a lever-type connector, a lever is mounted on one connector housing and a cam pin engageable with a cam groove of the lever is formed on the other connector housing. By rotating the lever after entering the connector housing, the two connector housings are further brought closer to each other to reach the proper fitting state. In this type of connector, it is necessary to hold the lever in the initial position so that the cam pin can correctly enter the cam groove.

As means for holding the lever in the initial position, there is a means disclosed in Japanese Patent Application Laid-Open No. 6-275337. This is, as shown in FIGS. 17 and 18,
The lever 1 is provided with an elastically deformable locking projection 2 which is engaged with the cam pin escape groove 4 of the connector housing 3 so that the rotation of the lever 1 in the initial position is restricted. When the connector housings 3 and 5 are fitted together, as shown in FIG. 19, the cam pins 6 engage with the locking projections 2 in the process of entering the cam grooves 7 to thereby disengage the cam pin escape grooves. 4 to release the rotation restriction of the lever 1.

SUMMARY OF THE INVENTION In the above prior art,
As a member for removing the locking projection 2 from the cam pin escape groove 4,
The cam pins 6 that protrude greatly into the cam grooves 7 are used.
For this reason, as shown in FIG. 19, even after the locking projection 2 is disengaged from the cam pin escape groove 4 and the rotation restriction of the lever 1 is released, the locking projection 2 crosses the cam groove 7. It will be greatly bent. As described above, in the related art, since the amount of bending of the locking projection 2 becomes larger than necessary, the reaction force due to the elastic restoring force of the locking projection 2 increases, and the workability at the time of fitting the connector housing is improved. This has led to a reduction in operability when the lever is rotated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to minimize the displacement of a locking projection when releasing the restriction on the rotation of a lever.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 Embodiment 1 of the present invention will be described below with reference to FIGS. The lever-type connector according to the present embodiment includes a male connector 10, a female connector 20, and a lever 30.

The female connector 20 includes a connector housing (one connector housing which is a constituent element of the present invention) 21 in which a terminal (not shown) is accommodated, and the connector housing 21 facing the male connector 10. And a hood portion 22 integrally formed so as to protrude forward. On both side surfaces of the connector housing 21, support shafts 23, 23 coaxial with each other are formed so as to protrude.
, A lever 30 is rotatably mounted as described later. Hood portions 2 are provided on both sides of connector housing 21.
2 are formed with engagement grooves 24, 24 that are open at the front end. The engagement groove 24 is cut out along the fitting direction with respect to the male connector 10. As described later, the lever 3 is provided on the upper edge of the engagement groove 24 in FIGS.
A locking projection 35 for holding the 0 in a predetermined initial position is engaged. The engagement groove 24 is formed so that the cam pin 12 of the male connector 10 described later
A relief groove is also used to avoid interference with the hood portion 22 when the fittings 0 and 20 are fitted.

The lever 30 comprises an operating portion 31 parallel to the support shaft 23 and a pair of plate-like mounting portions 32 formed at both ends of the operating portion 31. A shaft hole 33 into which the support shaft 23 is fitted is formed through the inner and outer surfaces of the mounting portion 32, and a cam pin 12 of the male connector 10 described later is formed on an inner surface of the mounting portion 32. A spiral cam groove 34 to be combined is formed. This cam groove 34
Is set smaller than the groove width of the engaging groove 24, and the cam groove 34 and the engaging groove 24 are arranged so that their center lines coincide with each other.

The lever 30 is in an initial position when the connection between the connectors 10 and 20 is started (see FIGS. 2 and 3).
And a completed posture (see FIG. 4) in which the fitting of the connectors 10 and 20 is completed. When the lever 30 is in the initial position, the opening 34A at one end of the cam groove 34 is arranged so as to face the male connector 10, and in this state, the cam pins 12 can be introduced into the cam groove 34. .

The lever 30 has two connectors 10,
A locking projection 35 is provided for holding the lever 30 in the above-mentioned initial posture when the lever 20 is not fitted.
The locking protrusion 35 is formed to protrude inward at one (upper side in FIGS. 2 to 4) groove edge of the opening 34A of the cam groove 34, and the lever 30 is in the initial posture. At the outer edge of the engagement groove 24. Due to the engagement between the locking projection 35 and the engagement groove 24, the lever 30 is held in the initial posture in a state where the clockwise rotation in FIGS. 2 to 4 is restricted. The locking projection 35 is formed so that the cam pin 12 is
4 to 2 when the introduction trajectory is introduced in FIG.
Are arranged at positions deviated from above. Therefore, the locking projection 35 does not interfere with the cam pin 12.

The male connector 10 includes a connector housing (the other connector housing which is a constituent element of the present invention) 11 in which a terminal (not shown) is accommodated, and a pair of protrusions formed on both side surfaces of the connector housing 11. The cam pins 12 and 12 are provided. The cam pin 12 exerts a cam function of forcibly pulling the connectors 10 and 20 in the initial stage of fitting to the fitting completed position by engaging with the cam groove 34 of the lever 30.

On both side surfaces of the connector housing 11, pressing portions 13 for releasing the engagement of the locking projections 35 with the engagement grooves 24 are provided as members separate from the cam pins 12. The pressing portion 13 is formed in a region that protrudes to the upper and lower sides in FIGS. 2 to 4 with respect to the cam pin 12,
When the two connectors 10 and 20 are fitted together, they have a rectangular pedestal shape so as to be fitted almost tightly into the engagement groove 24. The pressing portion 13 has an edge portion partially continuous with the base end portion of the cam pin 12, and the female connector 2 is provided at both sides of the cam pin 12 in this continuous portion.
The guide surface 14 is formed at an oblique angle with respect to the fitting direction with zero. Further, the height of the pressing portion 13 from the connector housing 11 is set lower than the cam pin 12, and is set to be flush with the outer surface of the hood portion 22 when fitted into the engagement groove 24. .

The upper and lower ends in FIG. 2 to FIG. 4 of the pressing portion 13 correspond to the outer region of the introduction trajectory when the cam pin 12 is introduced into the cam groove 34 as the connectors 10 and 20 are fitted. It moves into the engagement groove 24 while moving. The pressing portion 13 that has entered the engagement groove 24 is
By engaging the locking projection 35 of the lever 30 from the inside, the locking projection 35 is displaced outward until it comes off the edge of the engagement groove 24.

Next, the operation of the present embodiment will be described. In a state where both connectors 10 and 20 are not fitted, FIG.
As shown in FIGS. 5 and 7, since the locking projection 35 enters the engagement groove 24 from the outer surface side and engages with the groove edge,
The lever 30 is held in an initial position that allows the cam pin 12 to enter the cam groove 34. When the male connector 10 is fitted into the hood 22 of the female connector 20 from such a state, the cam pins 12
Enter within 4. With this, the pressing portion 1 is inserted into the engagement groove 24.
3, the guide surface 14 at the tip thereof comes into contact with the locking projection 35, and the locking projection 35 is gradually displaced outward according to the inclination of the guide surface 14 and rides on the outer surface of the pressing portion 13. It goes up. At this time, the mounting portions 32 at both ends of the lever 30 are elastically bent so as to expand with the displacement of the locking projection 35. Thus, the locking projection 35
Is pushed out by the pressing portion 13,
As shown in FIG. 6 and FIG.
And the lever 30 is allowed to rotate.

When the rotation restriction of the lever 30 is released in this way, the lever 30 is rotated clockwise from the initial position shown in FIG. Then, the male connector 10 is drawn relatively to the female connector 20 by the cam action of the cam pin 12 and the cam groove 34, and as shown in FIG. At this point, the fitting operation is completed. As described above, in the present embodiment, the locking projection 35 for holding the lever 30 in the initial posture in the rotation-restricted state is provided by the introduction of the cam pin 12 when the cam pin 12 is introduced into the cam groove 34. It is provided at a position off the track. And this locking projection 3
5 is provided as a separate member from the cam pin 12 for displacing the pressing member 5 in the regulation release direction.
3 is formed at a height lower than the cam pin 12 so as to engage with the locking projection 35 outside the cam groove 34. With this configuration, unlike the case where the restriction is released by engaging the cam pin with the locking projection, the locking projection 35 is not greatly displaced so as to cross the inside of the cam groove 34. In the present embodiment, the displacement of the locking projection 35 is small. Accordingly, the elastic restoring force generated by the lever 30 being bent in the expanding direction due to the displacement of the locking projection 35 is suppressed to a small value, and when the lever 30 is rotated, the elastic restoring force of the lever 30 is reduced. Since the frictional resistance due to the force is reduced, the operability is excellent.

Further, the timing of the completion of the introduction of the cam pin 12 into the cam groove 34 and the timing of the release of the rotation restriction by the pressing portion 13 are determined by the cam pin 12, the pressing portion 13, and the locking projection 35.
In the present embodiment, the pressing portion 13 is provided as a separate member from the cam pin 12, so that both timings are set as compared with the case where the rotation restriction is released by the cam pin. Has a higher degree of freedom. Further, in the present embodiment, the guide surface 14 is formed at the tip of the pressing portion 13 so that the engagement between the locking projection 35 and the pressing portion 13 does not cause the catching. In this case, a decrease in operability is avoided.

Further, in the present embodiment, the outer surface of the pressing portion 13 is flush with the outer surface of the hood portion 22 and the pressing portion 13
Are fitted closely into the engagement grooves 24 so that there is no large step or groove between the outer surface of the pressing portion 13 and the outer surface of the hood portion 22. Therefore, when the locking projection 35 moves between the outer surface of the pressing portion 13 and the outer surface of the hood portion 22 in accordance with the rotation operation of the lever 30, the operation resistance does not greatly change, and the operation feeling does not change. Is excellent.

Further, in this embodiment, the engaging groove 24 also serves as a relief groove for avoiding interference between the cam pin 12 and the hood portion 22, so that compared to a case where these grooves are separately formed. The notch area of the hood portion 22 can be reduced,
A reduction in the strength of the hood portion 22 caused by enlarging the cutout region is prevented. Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS.
